This is Eric Weinstein’s 2025 UCSD lecture about Geometric Unity. Data from DESI, published on 19 March 2025, might indicate a problem with the ΛCDM model. Eric Weinstein's Geometric Unity opens up a possibility for a time dependent cosmological constant. Data from Rubin Observatory might bring more insights in the near future. An interesting aspect of Geometric Unity is the unification of Riemannian and Ehresmannian Geometry, which looks like a squaring the circle problem.
